Mercedes-Benz USA is recalling ~93,000 model year 2023-2025 GLC 300, GLC 300 4MATIC, 2024-2025 AMG GLC 43 4MATIC, 2025 GLC 350E 4MATIC, and AMG GLC 63 S E vehicles equipped with a panoramic sunroof, according to the mandatory recall document made public today by the National Highway Traffic Safety Administration.
“In certain crash scenarios, where the rear occupant’s head contacts the C-pillar, the pillar may not absorb an adequate amount of the impact. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 201, “Occupant Protection in Interior,” MBUSA told NHTSA.
“An increased risk of injury for rear seat occupants during an unbelted crash scenario without airbag deployment (as defined in FMVSS 201u) cannot be ruled out. Subsequently, the requirements of FMVSS 201u might not be fulfilled. Due to a deviation in the development process, the damping of the rear roof lining might be too stiff for a specific FMVSS 201u test scenario,” Mercedes said.
Dealers will modify the roof lining and C-pillar trim, free of charge as required by U.S. safety regulations. Owner notification letters are expected to be mailed 4 August 2025. Owners may contact MBUSA customer service at 1-800-367-6372.Owners may also contact the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1-888-327-4236 (TTY 1-888-275-9171) or go to www.nhtsa.gov about NHTSA recall25V379 or 25V-379.
